adsl profile show [profile] Displays the specified ADSL profile or all ADSL profiles if you
do not specify one.

The profile is a table that contains information on ADSL line
configuration. Each entry in this table reflects a parameter
defined by a manager, which can be used to configure the
ADSL line.
Note that the default value will be used for any of the above
fields that are omitted.
The upstream rate must be less than or equal to the
downstream rate.
Even though you can specify arbitrary numbers in the profile
set command, the actual rate is always a multiple of 32 Kbps. If
you enter a rate that is not a multiple of 32 Kbps, the actual
rate will be the next lower multiple of 32 Kbps. For instance, if
you specify 60 Kbps for a port, the actual rate for that port will
not exceed 32 Kbps, and if you specify 66 Kbps, the actual rate
will not be over 64 Kbps.
The ADSL up/down shift noise margins define the threshold
that triggers rate adaptation. For example:
The target SNR is 6, and the up/down shift noise margins are
9/3.
If the signal becomes better and the SNR is higher than 9, rate
adaptation is triggered and the line rate becomes higher
If the signal becomes bad and the SNR is lower than 3, rate
adaptation is triggered and the line rate becomes lower.
After you create an ADSL profile, you can assign it to any of
the ADSL ports on any of the ADSL IES-612-51 in the IES-
612-51.
